Function Documentation

can_see()

static bool can_see ( const unit &  viewer, const map_location &  loc, const std::map< map_location, int > *  jamming = nullptr  )

static

Determines if loc is within viewer's visual range.

This is a moderately expensive function (vision is recalculated with each call), so avoid using it heavily. If jamming is left as nullptr, the jamming map is also calculated with each invocation.
